A generalised-$k_t$ jet algorithm for Deep Inelastic Scattering / van Beekveld, Melissa (NIKHEF, Amsterdam) ; Ferrario Ravasio, Silvia (Turin U.) ; Karlberg, Alexander (Oxford U., Theor. Phys. ; CERN) ; Peake, Darcy (Sussex U.)
We introduce an inclusive generalised-$k_t$ jet algorithm for Deep Inelastic Scattering, defined in the Breit frame and implemented in fjcontrib. [...]

How traversable is a traversable wormhole? / Freivogel, Ben (U. Amsterdam, GRAPPA) ; Fumagalli, Alessandro (U. Amsterdam, GRAPPA) ; Tomašević, Marija (CERN)
To answer the above question, we study low-frequency scattering in the four-dimensional traversable wormhole of Maldacena, Milekhin, and Popov. [...]

Constraining the real scalar singlet extension of the SM / Bosse, Moritz (Dortmund U.) ; Hiller, Gudrun (Dortmund U. ; CERN) ; Litim, Daniel (Sussex U.) ; Maltoni, Fabio (CERN ; Louvain U., CP3 ; Bologna U.) ; Ramsey-Musolf, Michael J. (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U. ; Caltech) ; Tentori, Simone (Louvain U., CP3) ; Xia, Guotao (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U.)
The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and improve the stability of the electroweak vacuum. [...]

CMB Constraints on Pre-Inflationary Axion Dark Matter Isocurvature / Petretti, Catherine (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Singh, Praniti (Brown U. (main)) ; Braglia, Matteo (CERN) ; Chen, Xingang (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Fan, JiJi (Brown U. (main) ; Brown U.) ; Li, Lingfeng (Nanjing Normal U. ; ICTP-AP, Beijing)
Although measurements of the Cosmic Microwave Background (CMB) are consistent with a nearly scale-invariant primordial spectrum of adiabatic perturbations, in which the energy densities of different components (radiation, baryons, and dark matter) fluctuate proportionally, there could also exist isocurvature perturbations, in which density fluctuations of the individual components differ from the adiabatic mode.

Testing F-theory GUTs with the Axiverse / Nee, Michael (Harvard U.) ; Reig, Mario (CERN) ; Weigand, Timo (U. Hamburg (main))
We show that axions coupled to photons in F-theory Grand Unified Theories (GUTs) satisfy the coupling-to-mass relation $g_{aγ}/m_a \leq C\, \frac{α_{\rm em}}{2π}\frac{1}{m_πf_π}$, with $C$ a calculable coefficient. [...]

Detector performance at SHiP for cascade-produced long-lived particles / Climescu, Matei (Gent U.) ; Kyselov, Yehor (Taras Shevchenko U.) ; Ovchynnikov, Maksym (CERN)
Previous studies have shown that cascade production in the thick target of the SHiP experiment may substantially enhance the number of light long-lived particles (LLPs) decaying in the fiducial volume. [...]

BPS Non-Renormalization in the BMN Matrix Model / Colin-Ellerin, Sean (CERN) ; Papadodimas, Kyriakos (CERN)
We show in the $(0+1)$-dimensional Berenstein-Maldacena-Nastase matrix model, dual to M-theory on a pp-wave background, that the coupling can be changed between any two finite, non-zero values using a special class of deformations, known as conjugation deformations. [...]

The production of a top-antitop quark pair in association with a $W$ boson constitutes one of the heaviest final states currently studied at the Large Hadron Collider (LHC) at CERN. [...]

Closing the loop on $Φ^4$ in AdS$_3$ / Carmi, Dean (Haifa U. ; CERN) ; Ciccone, Riccardo (Haifa U. ; CERN) ; Sukholuski, Shimon (Haifa U. ; Technion)
We compute the one-loop correction to the CFT data of all double-trace operators $[ϕϕ]_{n,\ell}$ for a $Φ^4$ theory in AdS$_3$, for arbitrary values of $n$, $\ell$, and of the scaling dimension $Δ_ϕ>1$. [...]

Stochastic Dynamics of Heavy Quarks in Strongly Coupled Plasma / Rajagopal, Krishna (MIT) ; Scheihing-Hitschfeld, Bruno (UC, Santa Barbara (main)) ; Wiedemann, Urs Achim (CERN)
We study the stochastic dynamics of heavy quarks propagating through the strongly coupled plasma of $\mathcal{N}=4$ supersymmetric Yang-Mills (SYM) theory at nonzero temperature in terms of the corresponding Kolmogorov equation, which correctly describes their kinetic equilibration and the non-Gaussian fluctuations in their momenta without having to restrict their velocity to the non-relativistic regime.
